Won a auction for a sky box, seller charged us £5.99 for the postage. I thought it was a bit cheap. Last night I received a message from the seller asking for a contribution towards postage because it had cost £14.85 someone else posted it for her. I said to my husband that it was a bit cheeky but I will wait for the package to make sure its all working then send her another £4-£5. This morning the package arrived and the postage was paid with a franking machine. I am guessing someone used their work franking machine and I am not sure if I should send a snotty message or pay some more £ towards postage.
